Requirements

To use Spark NLP you need the following requirements:

Java 8
Apache Spark 3.1.x (or 3.0.x, or 2.4.x, or 2.3.x)

Quick Start

This is a quick example of how to use Spark NLP pre-trained pipeline in Python and PySpark:

$ java -version
# should be Java 8 (Oracle or OpenJDK)
$ conda create -n sparknlp python=3.7 -y
$ conda activate sparknlp
# spark-nlp by default is based on pyspark 3.x
$ pip install spark-nlp==3.0.0 pyspark==3.1.1

In Python console or Jupyter Python3 kernel:

# Import Spark NLP
from sparknlp.base import *
from sparknlp.annotator import *
from sparknlp.pretrained import PretrainedPipeline
import sparknlp

# Start SparkSession with Spark NLP
# start() functions has 4 parameters: gpu, spark23, spark24, and memory
# sparknlp.start(gpu=True) will start the session with GPU support
# sparknlp.start(spark23=True) is when you have Apache Spark 2.3.x installed
# sparknlp.start(spark24=True) is when you have Apache Spark 2.4.x installed
# sparknlp.start(memory="16G") to change the default driver memory in SparkSession
spark = sparknlp.start()

# Download a pre-trained pipeline
pipeline = PretrainedPipeline('explain_document_dl', lang='en')

# Your testing dataset
text = """
The Mona Lisa is a 16th century oil painting created by Leonardo.
It's held at the Louvre in Paris.
"""

# Annotate your testing dataset
result = pipeline.annotate(text)

# What's in the pipeline
list(result.keys())
Output: ['entities', 'stem', 'checked', 'lemma', 'document',
'pos', 'token', 'ner', 'embeddings', 'sentence']

# Check the results
result['entities']
Output: ['Mona Lisa', 'Leonardo', 'Louvre', 'Paris']

If you are interested, there is a simple SBT project for Spark NLP to guide you on how to use it in your projects Spark NLP SBT Starter

Python

Python without explicit Pyspark installation

Pip/Conda

If you installed pyspark through pip/conda, you can install spark-nlp through the same channel.

Pip:

pip install spark-nlp==3.0.0

Conda:

conda install -c johnsnowlabs spark-nlp

PyPI spark-nlp package / Anaconda spark-nlp package

Then you'll have to create a SparkSession either from Spark NLP:

import sparknlp

spark = sparknlp.start()

or manually:

spark = SparkSession.builder \
    .appName("Spark NLP")\
    .master("local[4]")\
    .config("spark.driver.memory","16G")\
    .config("spark.driver.maxResultSize", "0") \    
    .config("spark.kryoserializer.buffer.max", "2000M")\
    .config("spark.jars.packages", "com.johnsnowlabs.nlp:spark-nlp_2.12:3.0.0")\
    .getOrCreate()

If using local jars, you can use spark.jars instead for comma-delimited jar files. For cluster setups, of course, you'll have to put the jars in a reachable location for all driver and executor nodes.

Quick example:

import sparknlp
from sparknlp.pretrained import PretrainedPipeline

#create or get Spark Session

spark = sparknlp.start()

sparknlp.version()
spark.version

#download, load and annotate a text by pre-trained pipeline

pipeline = PretrainedPipeline('recognize_entities_dl', 'en')
result = pipeline.annotate('The Mona Lisa is a 16th century oil painting created by Leonardo')

Compiled JARs

Build from source

spark-nlp

FAT-JAR for CPU on Apache Spark 3.x.x

sbt assembly

FAT-JAR for GPU on Apache Spark 3.x.x

sbt -Dis_gpu=true assembly

FAT-JAR for CPU on Apache Spark 2.4.x

sbt -Dis_spark24=true assembly

FAT-JAR for GPU on Apache Spark 2.4.x

sbt -Dis_gpu=true -Dis_spark24=true assembly

FAT-JAR for CPU on Apache Spark 2.3.x

sbt -Dis_spark23=true assembly

FAT-JAR for GPU on Apache Spark 2.3.x

sbt -Dis_gpu=true -Dis_spark23=true assembly

Using the jar manually

If for some reason you need to use the JAR, you can either download the Fat JARs provided here or download it from Maven Central.

To add JARs to spark programs use the --jars option:

spark-shell --jars spark-nlp.jar

The preferred way to use the library when running spark programs is using the --packages option as specified in the spark-packages section.

Apache Zeppelin

Use either one of the following options

Add the following Maven Coordinates to the interpreter's library list

com.johnsnowlabs.nlp:spark-nlp_2.12:3.0.0

Add a path to pre-built jar from here in the interpreter's library list making sure the jar is available to driver path

Python in Zeppelin

Apart from the previous step, install the python module through pip

pip install spark-nlp==3.0.0

Or you can install spark-nlp from inside Zeppelin by using Conda:

python.conda install -c johnsnowlabs spark-nlp

Configure Zeppelin properly, use cells with %spark.pyspark or any interpreter name you chose.

Finally, in Zeppelin interpreter settings, make sure you set properly zeppelin.python to the python you want to use and install the pip library with (e.g. python3).

An alternative option would be to set SPARK_SUBMIT_OPTIONS (zeppelin-env.sh) and make sure --packages is there as shown earlier since it includes both scala and python side installation.

Q: What if I am still on Zeppelin 0.8.x that only supports Apache Spark 2.4.x?

A: You can simply use the spark-nlp-spark24:3.0.0 package or Fat JAR instead.

Jupyter Notebook (Python)

Recomended:

The easiest way to get this done on Linux and macOS is to simply install spark-nlp and pyspark PyPI packages and launch the Jupyter from the same Python environment:

$ conda create -n sparknlp python=3.7 -y
$ conda activate sparknlp
# spark-nlp by default is based on pyspark 3.x
$ pip install spark-nlp==3.0.0 pyspark==3.1.1 jupyter
$ jupyter notebook

The you can use python3 kernel to run your code with creating SparkSession via spark = sparknlp.start().

Optional:

If you are in different operating systems and require to make Jupyter Notebook run by using pyspark, you can follow these steps:

export SPARK_HOME=/path/to/your/spark/folder
export PYSPARK_PYTHON=python3
export PYSPARK_DRIVER_PYTHON=jupyter
export PYSPARK_DRIVER_PYTHON_OPTS=notebook

pyspark --packages com.johnsnowlabs.nlp:spark-nlp_2.12:3.0.0

Alternatively, you can mix in using --jars option for pyspark + pip install spark-nlp

If not using pyspark at all, you'll have to run the instructions pointed here

Google Colab Notebook

Google Colab is perhaps the easiest way to get started with spark-nlp. It requires no installation or setup other than having a Google account.

Run the following code in Google Colab notebook and start using spark-nlp right away.

# This is only to setup PySpark and Spark NLP on Colab
!wget -q https://s3.amazonaws.com/auxdata.johnsnowlabs.com/public/scripts/colab/colab_setup.sh
!bash colab_setup.sh

This script comes with the two options to define pyspark and spark-nlp versions via options:

# -p is for pyspark
# -s is for spark-nlp
# by default they are set to the latest
!bash colab_setup.sh -p 3.1.1 -s 3.0.0

Spark NLP quick start on Google Colab is a live demo on Google Colab that performs named entity recognitions and sentiment analysis by using Spark NLP pretrained pipelines.

Kaggle Kernel

Run the following code in Kaggle Kernel and start using spark-nlp right away.

# Let's setup Kaggle for Spark NLP and PySpark
!curl -s https://s3.amazonaws.com/auxdata.johnsnowlabs.com/public/scripts/kaggle/kaggle_setup.sh | bash

Spark NLP quick start on Kaggle Kernel is a live demo on Kaggle Kernel that performs named entity recognitions by using Spark NLP pretrained pipeline.

Databricks Cluster

Create a cluster if you don't have one already
On a new cluster or existing one you need to add the following to the Advanced Options -> Spark tab:
```
spark.kryoserializer.buffer.max 2000M
spark.serializer org.apache.spark.serializer.KryoSerializer
```
In Libraries tab inside your cluster you need to follow these steps:

3.1. Install New -> PyPI -> spark-nlp -> Install

3.2. Install New -> Maven -> Coordinates -> com.johnsnowlabs.nlp:spark-nlp_2.12:3.0.0 -> Install
Now you can attach your notebook to the cluster and use Spark NLP!

NOTE: If you are launching a Databricks runtime that is not based on Apache Spark 3.x please choose a compatible Spark NLP package

EMR Cluster

To lanuch EMR cluster with Apache Spark/PySpark and Spark NLP correctly you need to have bootstrap and software configuration.

A sample of your bootstrap script

#!/bin/bash
set -x -e

echo -e 'export PYSPARK_PYTHON=/usr/bin/python3 
export HADOOP_CONF_DIR=/etc/hadoop/conf 
export SPARK_JARS_DIR=/usr/lib/spark/jars 
export SPARK_HOME=/usr/lib/spark' >> $HOME/.bashrc && source $HOME/.bashrc

sudo python3 -m pip install awscli boto spark-nlp

set +x
exit 0

A sample of your software configuration in JSON on S3 (must be public access):

[{
  "Classification": "spark-env",
  "Configurations": [{
    "Classification": "export",
    "Properties": {
      "PYSPARK_PYTHON": "/usr/bin/python3"
    }
  }]
},
{
  "Classification": "spark-defaults",
    "Properties": {
      "spark.yarn.stagingDir": "hdfs:///tmp",
      "spark.yarn.preserve.staging.files": "true",
      "spark.kryoserializer.buffer.max": "2000M",
      "spark.serializer": "org.apache.spark.serializer.KryoSerializer",
      "spark.driver.maxResultSize": "0",
      "spark.jars.packages": "com.johnsnowlabs.nlp:spark-nlp_2.12:3.0.0"
    }
}
]

A sample of AWS CLI to launch EMR cluster:

```.sh
aws emr create-cluster \
--name "Spark NLP 3.0.0" \
--release-label emr-6.2.0 \
--applications Name=Hadoop Name=Spark Name=Hive \
--instance-type m4.4xlarge \
--instance-count 3 \
--use-default-roles \
--log-uri "s3://<S3_BUCKET>/" \
--bootstrap-actions Path=s3://<S3_BUCKET>/emr-bootstrap.sh,Name=custome \
--configurations "https://<public_access>/sparknlp-config.json" \
--ec2-attributes KeyName=<your_ssh_key>,EmrManagedMasterSecurityGroup=<security_group_with_ssh>,EmrManagedSlaveSecurityGroup=<security_group_with_ssh> \
--profile <aws_profile_credentials>

S3 Cluster

With no Hadoop configuration

If your distributed storage is S3 and you don't have a standard Hadoop configuration (i.e. fs.defaultFS) You need to specify where in the cluster distributed storage you want to store Spark NLP's tmp files. First, decide where you want to put your application.conf file

import com.johnsnowlabs.util.ConfigLoader
ConfigLoader.setConfigPath("/somewhere/to/put/application.conf")

And then we need to put in such application.conf the following content

sparknlp {
  settings {
    cluster_tmp_dir = "somewhere in s3n:// path to some folder"
  }
}
